Malformação venolinfática em borda lateral de língua: relato de caso / Venolymphatic malformation in lateral edge of the tongue: case report

Resumo As malformações vasculares são anomalias que podem acometer veias, vasos linfáticos e artérias de forma isolada ou mista. Quando se apresentam de forma mista, com componentes venosos e linfáticos, são denominadas malformação venolinfática ou linfático-venosa, de acordo com sua constituição predominante. Embora seja um distúrbio benigno de bom prognóstico, é localmente invasivo, podendo levar a deformidade e havendo, ainda, a propensão de recorrência local. O presente artigo traz um caso de malformação venolinfática com localização incomum em borda lateral de língua, abordando-se a conduta clínica e o referencial teórico vigente.

Abstract Vascular malformations are vascular anomalies that can affect veins, lymphatic vessels, and/or arteries in isolated or mixed form. When they present in the mixed form with venous and lymphatic involvement, they are called venolymphatic or lymphatic-venous malformations, depending on their predominant component. Although these are benign disorders with good prognosis, they are locally invasive and may lead to deformity, while there is also a propensity for local recurrence. This article presents a case of venolymphatic malformation with unusual localization on the lateral border of the tongue, addressing the clinical conduct and the current theoretical framework.

Efectividad del propranolol en el tratamiento de malformaciones vasculares cutáneas / Effectiveness of propranolol in treatment of cutaneous vascular malformations

Se realizó un estudio cuasi-experimental de series temporales para evaluar la efectividad del propranolol en el tratamiento de malformaciones vasculares cutáneas en 48 pacientes que asistieron a la consulta del Servicio de Dermatología del Hospital Central Universitario Dr. Antonio María Pineda durante el período febrero-julio 2018. Los resultados muestran que existen diferencias estadísticamente significativas (p <0.05; p0,0001) antes y después del primer mes de tratamiento con propranolol, las cuales se mantiene hasta los seis meses, con respecto al tamaño, color, consistencia y temperatura. Se espera que los resultados sirvan para proponer el uso de propranolol como una opción terapéutica no invasiva en el tratamiento de las malformaciones vasculares cutáneas(AU)

A quasi-experimental study of time series was carried out to evaluate the effectiveness of propranolol in the treatment of cutaneous vascular malformations in 48 patients attending the Dermatology Service of the Hospital Central Universitario Dr. Antonio Maria Pineda during the period February - July 2018. The results show that there are statistically significant differences (p <0.05; p0,0001) before and after treatment with propranolol starting one month post-treatment which are kept until six months, related to size, color, consistency and temperature of lesions. We hope that these results will encourage the use of propranolol as a non-invasive therapeutic option in the treatment of cutaneous vascular malformations(AU)

Malformaciones Vasculares / Vascular malformation

Las malformaciones vasculares son anomalías presentes siempre desde el nacimiento que, al contrario de los hemangiomas, nunca desaparecen; pueden crecer durante toda la vida por hipertrofia. Según la clasificación de la ISSVA, las malformaciones vasculares se dividen en función del vaso afectado en capilares o venulares, venosas, linfáticas, arterio-venosas y combinadas o complejas. Cada una de ellas, con unas peculiaridades clínicas y hemodinámicas definitorias.

Vascular malformations are anomalies always present at birth that, contrary to hemangiomas, never regress; and may hypertrophy during lifetime. According to the ISSVA classification, vascular malformations are divided, depending on the affected vessel, into capillary or venular, venous, lymphatic, arteriovenous and combined or complex; each with certain defining clinical and haemodynamic peculiarities.

Embolization of congenital intrahepatic porto-systemic shunt by n-butyl cyanoacrylate.

Congenital intrahepatic portosystemic venous shunt (IHPSVS) is rare vascular anomaly. We present one case of a 14- month male child who presented with global developmental delay. Child had high ammonia levels with low glutamine and high bile salts on the previous investigations and had history of neonatal seizures since day 13 of life. On admission, serum ammonia levels were elevated to 112μmol/L. Other laboratory investigations including liver and renal function test, and electrolytes were normal. He was, diagnosed to have IHPSVS on the basis of Doppler and CT, and treated by embolization with n-butyl cyanoacrylate (glue). A brief review of diagnostic modalities and endovascular management for the IHPSVS is presented including the present case.

Multiple vascular anomalies in the abdomen: a gross anatomical study / Múltiples anomalías vasculares en el abdomen: un estudio anatómico macroscópico

Knowledge of the branching pattern of the abdominal aorta is clinically important for any abdominal surgeon operating on parts of the gut or neighboring structures like the suprarenals, spleen, pancreas, liver, kidneys and ureter. The presence of abnormal inferior phrenic artery associated with aberrant branch from the celiac trunk supplying the pancreas and duodenum is a rare anomaly. In the present case, we observed four branches of the celiac artery i.e. (a) left gastric artery (b) common hepatic artery (c) splenic artery and (d) an aberrant branch, which took a course inferiorly towards the pancreas. The aberrant artery supplied the body of the pancreas and gave a branch which supplied the horizontal part of the duodenum and then entered the transverse mesocolon to supply the hepatic flexure and some portions of the ascending and the transverse colon. The inferior phrenic artery was absent on the left side. Concomitant anomalies of such type are to be kept in mind by the surgeon, while operating cases of carcinoma head of pancreas and performing kidney transplantations.

El conocimiento del patrón de ramificación de la aorta abdominal es clínicamente importante para cualquier cirujano abdominal que opere en partes del intestino o estructuras vecinas, como glándulas suprarenales, bazo, páncreas, hígado, riñones y uréteres. La presencia anormal de la arteria frénica inferior asociada con una rama aberrante originada del tronco celiaco, supliendo el páncreas y duodeno, es una variación anatómica rara. En el presente caso, se observaron cuatro ramas de la arteria celiaca: (a) arteria gástrica izquierda (b) arteria hepática común (c) arteria esplénica y (d) una rama aberrante, que tuvo un curso inferior hacia el páncreas. La arteria aberrante suministraba irrigación al cuerpo del páncreas y daba una rama para la parte horizontal del duodeno para luego entrar en el mesocolon transverso para irrigar la flexura hepática y algunas partes del colon ascendente y transverso. La arteria frénica inferior estaba ausente en el lado izquierdo. Anomalías concomitantes de este tipo deben ser consideradas por el cirujano, en casos de operación de carcinoma de cabeza de páncreas y la realización de trasplante renal.
